What is the best definition of acerbic?
Acerbic (adjective) – sharply harsh, sarcastic, or ironic in expression or mood; or, sour or bitter in taste
GRE pro tips:
Acerbic sounds like acidic, and both words are, in fact, derived from equivalent Latin roots: the roots acer, acid, and acri all mean “bitter, sour, or sharp.” So it makes sense that the word acerbic can be used to describe food that tastes acidic, or sharply bitter and sour. However, on the GRE, acerbic is more likely to be used to describe acidic (sharp or biting) moods, expressions, or tones.
Now, the word acerbic usually (but not always) takes on a fairly negative connotation. For instance, acerbic can describe personal attacks, comments, or critical reviews that are unduly bitter or sarcastic and have a caustic effect. On the other hand, it can be used to describe an “acerbic wit” – one that is sharp and sarcastic but nevertheless impressive or endearing. So, a person (or, perhaps, a work of writing) that is described as acerbic could be harsh, bitter, and quite unlikeable; or, they/it could be sharp and sarcastic, in a witty way (and so likeable, at least to some).
